About this site

Jan 01, 2013  A general mathematical model of coal miners’ unsafe behavior has been established from the perspective of behavioral game theory to find new ways of quantitatively studying coal mine safety management practice. This model is based on the above discussion and uses a relative theoretical model for reference [6], [7].
